IMPROVEMENT IN WAGON*BRAKES.

Specification forming part of Letters Patent No. 13?.633, dated API il 8, 1873; application filed December 9, 1872.

2, a vertical longitudinal section of the same taken on the line 0 0, Fig. 1.

The invention consists in the mprovement of wagon-brakes, as hereinafter desoribed and pointed out in the claim.

In the drawing, the letter A represents the front axle of the wagon. Bis the rear axle thereof; 0, the reach; D, the front bolster rigidly connected with the reach. E is the brake-beam, supported in the middle by a strap, a, whieh is fastened to the under side of the reaeh. At the ends the brake-beam may be steadied and partly supported by short chains b b that connect it With the wagon-body. cl is a spring, secured in the strap a, and bearing a-gainst the back of the brake-beamin the manner shown, to hold the sa'me'as far forward as possible, and thus keep the brake-shoes e e oi' the hind wheels F. By means of short chains f f the brak-beam is connected With two levers, G G, which are by a pin, pivoted to the reach behind the beam E. The connection of the beam E with the levers G is made with the short ends of the latter; their long ends or arms are by rods IL /L conneeted Witli a lever, H, which is pivoted to the front of the wagon-body, or to any suitable projection et the front bolster.

When the lever H is swung back by the driver of the wagon the long arms of the levers G G Will be swung forward and their short arms thereby oarried baok, so that they Will draw the beam E back in equal degree on eaehside of the reach, and thereby firmly apply the brake-shoes against the wheels F. The rods h h have parts formed of ohains, so that the same oan be extended or contracted at will, in conformity With the contraction or extension of the wagon-mach, if il: should be fonnd necessary to vary the length of the same.

Having thus described my invention, I claim Vitnesses:
